Get an asset's current peg state

Timestamp of the most recent transition into the current state. Equals the current snapshot timestamp if the engine has only ever observed one state for this asset.

true when updated_at is older than the 15-minute freshness bound the list/detail endpoints enforce — i.e. the feed has likely frozen. Unlike list/detail, /state still returns the last value rather than 404-hiding it; read this flag to fail safe. Consumers needing a tighter bound can derive their own from updated_at.

Class-aware peg state. Mirrors the engine PegState enum and the peg_state Postgres enum. Used for state, from_state, and to_state fields across the API.

The state is CLASS-AWARE: an LST reading a −1.4% discount (normal unstaking spread) is PEGGED, while a fiat stable at far less would be DRIFT. Trust this value directly rather than imposing a naive discount cut.

Timestamp the current snapshot was computed (the latest discount_snapshots.ts). Distinct from since (state-transition time): this is the FRESHNESS signal. The engine stops writing snapshots when a feed goes stale ("missing data is not confirming data" — H8), so a frozen updated_at is exactly how a stale/frozen feed surfaces on this endpoint.
